How do I size a long pipeline between two atmospheric tanks for gravity flow? The tanks are separated by about 10 kms and have a 100 m elevation difference.
Is selecting a pipe size such that the static head available at destination is equal to the frictional line loss, a correct approach? However, to arrive at frictional line loss, I have to assume a specific flow rate and that the line is running full.

go-fish,
Have you checked within forum for similar topics in the past?
There is an excellent file related to the Gravity Flow uploaded by Art Montemayor. You can download it at: http://www.cheresour...rocess-vessels/ and also read in interesting discussion.

In order to give meaningful advice we need more information. Is the pipe an overflow or a flooded outlet from the first tank? How and where is the flow controlled? Is the flow continuous or intermittent? Are there any low points or high points along the route? What is the fluid?
You say that you would have to assume a specific flowrate. In sizing a line you always have to do it for a specific flowrate, or maybe a range of flowrates. There is nothing unusual about this. Whether the pipe runs full or not depends on the answers to my questions above.
